Waveguides with a record propagation length of 250 μm fabricated at FMN Laboratory

11 february 2021

FMN Lab team jointly with Rosatom Enterprise researchers developed a technology for creating plasmon waveguides based on thin gold films with a record propagation length of 250 μm.

New waveguides with unique properties will find application in waveguide optical sensors, highly sensitive plasmon sensors, and optical interconnects for new generation processors.

The new technology is currently used to create ultrasensitive optical gas sensors (please, see for details).

The material is based on the article Quarter-Millimeter Propagating Plasmons in Thin-Gold-Film-Based Waveguides for Visible Spectral Range in the Journal of Lightwave Technology.
